Why the radiation danger symbol? I know there are random number generators based on radioactive compounds, like Kr-85, coupled to a Geiger. Your generator works that way?
Correct. It uses the timing between radioactive decay emissions for entropy.
What's your radioactive source? Do you use a Geiger or a semiconductor detector?
10 uCI of Cs-137. It will be a Geiger tube. Prototyping the microcontroller now, then I’ll add the random source.
